[Feature Request] `OpenTelemetry` tracing integration

I noticed in the latest release notes for 8.2.0:
- https://github.com/Azure/AppConfiguration-DotnetProvider/releases/tag/8.2.0

That new Activities are now created for some of the actions performed by this package, with an activity source named `Microsoft.Extensions.Configuration.AzureAppConfiguration`.

With this in mind, could the team also provide an official instrumentation package for OpenTelemetry that listens on that activity source?

Usually, all traces and metrics are exposed to OTEL via one of those `OpenTelemetry.Instrumentation.*` packages, that either instrument the code themselves, or just tap into existing instrumentation (which I assume would be the case here).

In the meantime, my assumption is that we just need to call `AddSource("Microsoft.Extensions.Configuration.AzureAppConfiguration")` on the `TracerProviderBuilder` for the newly introduced activities to be propagated in a simplistic manner?
